African spear ID help

[Araña_del_Sol]

Hi all,

I got this spear a while back but was never sure where it came from though it always struck me as being Sudanese mainly due to the crocodile skin "sleeves" on either end of the shaft. It is fairly small with total length of 88.9 cm (35 inches). Any help identifying its place of origin and/or ethnic attributions would be appreciated.
